Frequently Asked Questions (FAQs)
Q1: What is companion planting and how does it work?
Companion planting positions plants together strategically so they benefit each other through pest deterrence, nitrogen fixation, pollinator attraction, or physical support. Plants release aromatic compounds, root chemicals, and physical structures that create mutually beneficial growing relationships. Our garden herb pairing guide covers the science and practice of companion planting in accessible, practical detail.
Q2: What are the best companion plants for a vegetable garden?
French marigolds, nasturtiums, borage, basil, dill, and chives are the most versatile and effective companion plants for any vegetable garden, offering broad-spectrum pest deterrence, pollinator attraction, and soil improvement benefits. Our food forest guide covers companion planting plant selection for productive vegetable and food growing gardens in comprehensive detail.
Q3: Which plants should not be planted together?
Fennel is allelopathically incompatible with most vegetables and should be grown separately. Onions inhibit bean and pea growth. Dill should never be planted near carrots or tomatoes. Potatoes and tomatoes are susceptible to the same blight diseases and should always be kept well separated throughout the growing garden.
Q4: How do I start a companion planting layout as a beginner?
Start with the simplest and most proven combinations — tomatoes with basil and marigolds, or the Three Sisters of corn, beans, and squash — before expanding to more complex guild arrangements. Our small vegetable gardens guide covers beginner companion planting layouts for raised beds and small gardens in excellent, encouraging, practical detail.
Conclusion
